AIS messages can be viewed, created and transmitted from the ‘Messages’ menu.

The available options are: Compose - takes you to the message composition screen Inbox - takes you to the received message list view Sent - shows a list of recently sent messages.

To compose a new message, select the type of message from the drop down menu and the destination. This can be by directly entering the MMSI, or by selecting from a list of visible targets.

The message text is entered using the on screen keyboard. Messages are limited to 80 characters in length.

Class B AIS transceivers are permitted to receive broadcast SRMs and broadcast text messages, however this function is not mandatory. Some Class B AIS transceivers are not able to receive addressed SRM or text messages. There is therefore no guarantee that text messages or SRMs sent by this device to a Class B AIS transceiver will be received.

4.6.9 Long range messages

If the AIS transceiver is connected to a long range communication system via the long range communications port then long range interrogations may be received. These are requests for information from a distant base station beyond normal AIS operation range.

The AIS transceiver can be configured to automatically respond to Long Range (LR) interrogations, or you can opt to respond to any interrogation manually. Automatic response is the default setting, but this can be changed on the ‘Home’ > ‘System settings’ > ‘Advanced’ > ‘Radio and Long range settings’ menu.

When a Long range interrogation is received you will be alerted by an onscreen pop-up message.

In automatic response mode simply review and acknowledge the notification screen using ‘Acknowledge’. In manual response mode you should review the request and select either the ‘Respond’ or ‘Decline’ option as appropriate.

4.11.2 Target filtering

From the ‘Target list’ options menu, if 'Show Filter Settings' is selected, a screen is displayed indicating which filter parameters can be set to reduce the amount of data displayed on screen. This screen can also be accessed through ‘Home’ > ‘System settings’ > ‘User settings’.

Filters can be toggled on and off on the ‘Target list’ by pressing the ‘Options menu’ key and selecting ‘Toggle Filters On / Off’. The bottom line of the ‘Target list’ shows how many targets are visible or filtered out. If a filter is set, the filter icon is displayed at the top of the screen. The Filters icon does not represent CPA/TCPA settings.

4.11.3 CPA/TCPA Settings

The AIS transceiver can be configured to identify approaching vessels which fall within certain limits. The Closest Point of Approach (CPA) defines a boundary around the own vessel upon which, if breached, will trigger an alert. Time to Closest Point of Approach (TCPA) can only be set if CPA is set, and will trigger the alert if the time to the CPA limit is breached.

These parameters are set on the ‘Home’ > ‘System settings’ > ‘User settings’ > ‘Filtering and CPA/TCPA Settings’ menu.

The target list shows targets which trigger the CPA/TCPA alert in red.

Page 56

Operation

These CPA/TCPA figures are calculated solely on AIS data and should not be used for anti-collision purposes.

Note: Setting the CPA/TCPA filter will not activate the Filters Icon.

4.11.4 Target plot

The ‘Target plot’ screen shows the location of other AIS equipped vessels and shore stations relative to your own vessel. The ‘Target plot’ screen provides a basic overview of AIS targets and should not be regarded as a substitute for display of AIS information on a dedicated electronic chart display system (ECDIS).

The plot range can be adjusted by rotating the scroll wheel which cycles through the ranges 0.1NM up to 100NM. The range relates to the radius of the outer range ring shown on the screen.

Individual targets can be selected by using the arrow keys. When selected a square outline will appear around the target and the vessel details will be shown on the left hand side of the screen.

By pressing the options menu key, additional display features can be selected. If the Own Vessel Details option is selected the left hand side of the screen will

change to show own vessel dynamic data. If the MOB Details Display option is selected, the target plot will change to

show only AIS-MOB, AIS-SART, and AIS-EPIRB devices. The left hand side of the screen will show the range and relative bearing to whichever target is currently highlighted using the arrow keys.

4.12 Micro SD card data input

On the front of the AIS transceiver under the cover on the lower left hand side is a socket for a Micro SD memory card. See Figure 25. This can be used to upgrade the unit firmware, display detailed charts or to log port data. Note the orientation of the Micro SD card, which is critical to ensure the product is not damaged.

Technical information

My MMSI is being received by other vessels but my vessel name is not shown on their chart plotter or PC.

External Sensors not being recognised.

VSWR Alarm Activated or High VSWR.

● Some older AIS devices and chart plotters do not process the specific class B message which provides the vessel name (message 24). This is not a fault of your AIS transceiver. Software upgrades are available for many older chart plotters which will correct this issue. The other vessel should update its AIS unit and / or chart plotting software to receive AIS message 24.

● Check Compatibility Mode option in the Interface Settings Menu.

● Check the Baud Rate set.

● Check the wiring is correct.

● Ensure VHF Antenna is as far away as possible from metallic structures and any other antennae.

● Ensure VHF Antenna is as high as possible.

● Ensure VHF Antenna is suitable for AIS i.e. 3dBi Gain, 156-162MHz, and uses high quality RG213 or RG214 cable.

● The VHF Antenna cable should be as short as possible and no more than 30 metres (100ft) in length.
